DATIVUS (DATIUS), JULIAN, VINCENT and OTHERS (Saints) Martyrs (January 27) (Date unknown.) These holy men, thirty in number, are usually described as having suffered for Christ in Africa in the third century, but Surius believes that they were victims of the Vandal persecution, two hundred years later. Another and perhaps very tenable opinion holds that they were martyred in Galicia in the north-west of Spain, and as early as A.D. 95. No particulars are known.
